Standalone copy problem

I’ve searched the forum and I’m picking up an earlier thread (Re: 4.6.1 Standalone Build Problem [message #79592 is a reply to message #79589 ]), but haven’t seen the solution.

MaxMSP 4.6.2, PB G4, OS 10.4.9.

I build a standalone to the boot partition, and it runs. But when I try to copy it to another partition or to an external firewire disk (to move to another machine for testing/distribution), I get:
‘The alias "MaxAPI" cannot be copied to the destination, perhaps because the destination does not support this type of alias.’

I still have MaxMSP 4.5.7 on the same system. Is that a problem?

P.S. I’d really like to build the app on a different partition, but there’s the "executable bit" problem. Is this explained in the regular documentation? Unix’ intestines are way beyond the "artist user" for whom Max is usually so great.
